-Stereo and rocking are powerful ways to show off the 3-D structure of your subjects.  With Zerene Stacker, they are now also easy!  Instead of shooting a separate stack for each viewing angle, Zerene Stacker allows you to take a __single__ stack and make multiple images that can become a stereo pair, a rocking animation, even rocking stereo.+Stereo and rocking are powerful ways to show off the 3-D structure of your subjects.  With Zerene Stacker, they are now also easy!  Instead of shooting a separate stack for each viewing angle, Zerene Stacker allows you to shoot a __single__ stack and then use synthetic rotation to make multiple images that can become a stereo pair, a rocking animation, even rocking stereo.

 Different stacks will need different shifts to make a good looking stereo pair.  To help in finding a good shift, Zerene Stacker provides a simple stereo previewing facility.  Just go to Tools > Stereo... > Start Preview.  This will set up two side-by-side synchronized windows that act like Retouching except that there’s no brush and you can choose whatever output image you want in either window.  Just click on the window, then click on an entry in the Output Images list.  Repeat for the other window, and adjust your selections until the two images work well together.   Different stacks will need different shifts to make a good looking stereo pair.  To help in finding a good shift, Zerene Stacker provides a simple stereo previewing facility.  Just go to Tools > Stereo... > Start Preview.  This will set up two side-by-side synchronized windows that act like Retouching except that there’s no brush and you can choose whatever output image you want in either window.  Just click on the window, then click on an entry in the Output Images list.  Repeat for the other window, and adjust your selections until the two images work well together.  
  
- +Note that for some stacks the images may initially appear in the wrong order, so that depth is inverted.  In that case, you can reverse the order of the images in preview with four mouse clicks: select left window, select the Output Image to appear in the left window, select right window, select Output Image to appear in the right window.  If you consistently find that you need to reverse the order in preview, you can also change Preferences so that the images are created in the opposite order to start with.  Simply go to Options > Preferences > Stereo/Rocking and swap the values for first and last image shifts.  For example if -3,+3 produces images in reversed order, then swap them to be +3,-3. 
  
 Here is what the screen looked like when Stereo Previewing the sample shown above.  The left window is showing image _002, as indicated by the highlighted title bar and highlighted image name.  The right window happens to be showing image _006, although we can’t tell that from this screen capture.   Here is what the screen looked like when Stereo Previewing the sample shown above.  The left window is showing image _002, as indicated by the highlighted title bar and highlighted image name.  The right window happens to be showing image _006, although we can’t tell that from this screen capture.

-To produce any other format, you must use some external program.  The free software StereoPhoto Maker (http://stereo.jpn.org/eng/stphmkr/) allows cropping and can generate output in a wide variety of formats, including color anaglyphs for viewing with red/cyan or red/green glasses.  Animated GIF images for rocking displays can be generated by programs such as Adobe’s ImageReady and the free GIMP software (http://www.gimp.org/).  Longer sequences can be generated as looping movies by programs such as Apple’s QuickTime Player Pro (http://www.apple.com/quicktime/pro/, for Macintosh or Windows).+To produce any other format, you must use some external program.  The free software StereoPhoto Maker (http://stereo.jpn.org/eng/stphmkr/) allows cropping and can generate output in a wide variety of formats, including color anaglyphs for viewing with red/cyan or red/green glasses.  Animated GIF images for rocking displays can be generated by programs such as Adobe’s ImageReady and the free GIMP software (http://www.gimp.org/).  It can also be done with regular Adobe Photoshop, using Timeline animation as described at [[https://helpx.adobe.com/photoshop/how-to/make-animated-gif.html]].  Longer sequences can be generated as looping moviesby programs such as Apple’s QuickTime Player Pro (http://www.apple.com/quicktime/pro/, for Macintosh or Windows).
